System for accessing digital television database through wireless signal

The invention relates to a system for digital television, which accesses a database in a digital television through a wireless signal and modifies the content of the database.

Currently in the documented remote control, it was first invented by Nikola Tesla, the father of AC power system, developed in 1898, and applied for and passed the US patent examination, number 613809, which is related to remote control. Apparatus and method of transportation. Later, the remote control was gradually developed in various fields, such as the space industry, video game instruments, computer equipment operations, camera industry, automatic doors, military or industrial production, etc. The controllable devices included at least television, toys, and transportation. Tools, electric motors or military equipment.

In modern times, it is quite common to use a remote control to control the starting or closing of electrical loads. The more common ones are like remote control garage door opening, car After the child enters, the remote control garage door is closed; the situation of the remote control lamp changes at any time according to the demand; the remote control electric window is cheap, the patient does not need to get out of bed to control; the remote control TV channel selection, the user does not need to go to the TV The front operation is the use of common remote controls.

After the popularity of TV sets, due to a large number of market demands, in order to seize market share, various manufacturers have developed in various technical fields, trying to find out the characteristics of the brand and increase the consumption power of consumers. Later, with the changing era of digitalization, television technology has evolved from analog TV to digital TV, realizing the comprehensive digitalization of TV program storage, editing and broadcasting. Similarly, other accompanying electrical equipment, such as video recorders, video cameras, air conditioners, electric fans, and DVD (Digital Versatile Disc) players have also been digitalized.

In general, as a remote controller for controlling an electronic device such as a television receiver, the ISM (Industrial, Scientific and Medical use) band in the 2.4 GHz band is selected for wireless communication, and is shielded from the infrared control method. The impact of the object is less, so the advantage of reaching a long distance, the manufacturer will choose the appropriate remote control method according to the needs and characteristics. Most importantly, TV remotes are mostly operated by battery power, so the circuit needs to be designed with low power to operate.

After the development of digital TV, the remote control has also become one of the development priorities. The number of TV channels is constantly rising. The more TV programs you can choose to watch, the more channels there are. In addition to domestic TV channels, network technology cooperation Digital TV, it will not be difficult to be able to watch foreign TV channels. In this case, users should be familiar with the switching modes of various channels, and they need to spend time habits and learning. Especially the operation mode of the remote control is complicated, and the number of buttons is large. For the elderly and children, it is really not a good thing to get started. Easy thing. In addition, digital TVs provide more functions than before, and the remote control has to add more buttons in order to remotely control its functions. Thus, the operation of the remote controller is more complicated, and learning and habits become a burden for the user.

As can be seen from the above, although the comprehensive digitalization of the TV brings many functions, the remote control system becomes more and more complicated. Although the current remote control is functionally capable of fully controlling the electrical equipment, it is not a simple matter for the first time user to fully understand and use the remote control to control the electrical equipment. In particular, the user is When using for the first time, it is always necessary to go through a long period of exploration to master the function usage and channel switching of the remote controller. When the digital TV is replaced, a new remote control will be attached, and the user needs to spend time getting used to the new remote control to operate the new digital TV, and the operation mode and button position of each brand remote controller are also different. It is not a convenient thing.

In view of this, the present invention intends to provide a more convenient remote control operation, and at the same time overcome the above disadvantages, so the inventors have studied hard, tried different methods, and a series of tests, while considering the cost, finally researched the present invention.
